1. A method of manufacturing a magnetic core comprising the steps of:
- forming a thin metal tape having a rolled face and a free face;
superimposing at least one of said free face of said metal tape to form at least a two-layer tape and said rolled face of said metal tape to form at least a two-layer tape, in a free-to-free or in a rolled-to-rolled relation; and
winding and laminating said two-layer tape into a given shape.
